ChaiScript is an embedded scripting language designed from the ground up to directly target C++ and take advantage of modern C++ development techniques. Being a native C++ application, it has some advantages over existing embedded scripting languages. It uses a header-only approach, which makes it easy to integrate with existing projects. It maintains type safety between your C++ application and user scripts. It supports a variety of C++ techniques including callbacks, overloaded functions, class methods, and STL containers.

P* (P-star) is a Web programming language that incorporates common tasks like template handling and database queries into the language. It features MySQL database access with prepared statements, HTML templates, standard arithmetic and variables, functions, structs, (to-be-classes), JSON output, and GET and POST. Programs can be run on the command line, in a CGI environment, or by the P* Apache Module.

Cainteoir Text-to-Speech is a GNOME/GTK+ GUI for the Cainteoir Text-to-Speech Engine. It allows you to listen to your documents or record them for use on the move using any of the eSpeak or MBROLA text-to-speech voices.

sqlpp11 is an embedded domain-specific language which allows programming SQL very naturally in modern C++. It also enables the compiler to detect syntax errors, type errors, name errors, and even some semantic errors before they ever hit unit tests or production. Queries can be constructed at compile time or run time, offering varying levels of safety and flexibility.

hbcxx is a tool that uses the Unix #!/path/to/interpreter shebang technique to make C++ source
code directly executable. It keeps coding fast and fun by making it unnecessary to write a build system and an install script for simple programs and quick and dirty personal toys.
